UNITED STATES PATENT orrlca;

This invention relatesto new and useful improvements inwjaste andoverflow equipment for bath tubs: 7

One object of the invention is to provide an apparatus of the characterdescribed specially designed for the purpose of controlling the wasteoutlet of a bath tub. l

Another object of the invention is to pro-' vide an apparatus of thecharacter described including a novel form of bath tub waste outlet witha novel type of valve controlling the same and a mechanism mounted in'the overflow pipe through which said valve may be conveniently operatedto open or close said valve.

A further feature ofthe invention is to provide an equipment of thecharacter described whose parts are readily accessible from the insideof the tub, for repairs, or replacements.

Finally the object of the invention-is to provide a bath tub equipmentof the character described, and for the purposes stated, which is' ofnovel butsimpleconstruction which may be easily installed, whose partsare readily accessible for repairs or replacements and which is veryconvenient and emcient in use.

With the above and other objects in view the invention has particularrelation to certain novel features of construction, operation andarrangement of parts, an example of which is given in this specificationand illustrated in the accompanying drawings,

wherein Figure 1 shows a vertical sectional View of the equipmentapplied to a bath tub.

Figure 2 shows a plan view of the waste outlet connection.

Figure 3 shows a vertical sectional view.

elbow which is connected into the T 3 through the outlet pipe 5. Theupper side of thls elbow has a tapering extension 6 which extends upthrough the o in the bottom of the tub at one en and surrounding thisextension, and fitted between 1t and the adjacent part of the tub thereis a washer 7 ofanysuitable material and a thimble 8 is threaded intothe elbow 4 and has an outwardl extending flange 9 overlapping'the waser'7 and clam it in place The 'lower end of the thlmble 8 is flared, asat 1 0,forming a valve seat and beneath it there is an outwardly openingvalve 11 whose upper side is formed to conform to the form of the seat10. Anchored to the bottom of the elbow are the spaced guides 12, 12,which upstand therefrom and project into the" guideways 13, 13, of thevalve, provided -to receive said guides.

These guides are provided 'to confine the valve to a vertical movement.

The'thimble 8 has inside projections, as

12 are accessible from the inside of the tub I and by removing saidthimble said other parts may be. removedfor repairs, or replacements. Anoverflow pipe 15 is con- I nected to the upper end of the T 3 and .anoverflow elbow 16 is connected to the upper end of the overflow pipe 15,by means of the ball joint 15. This connection is made by a suitablelock nut 16' and permits a suitable adjustment of said connected parts.The elbow 16 is provided with the annular flange 17 which abuts theoutside of the tub 1 and the inner end of said elbow is fitted through asuitable opening in the end of the tub near the top and .is outwardlythreaded to receive a lock nut 18 which, when screwed home, abutsagainst the inside of the tub and retains the packing washer 19 inplace, as well as securing the overflow elbow to the tub. The washer 19may be removed and replaced from the inside of the tub by removing thenut 18.

The inwardly projecting end of the elbow 16 is provided with a spider 20having a central bearing 21, formed with a side slot 22. There is anoperating rod 23 whoseinner end carries a suitable grip, o1 handle 24,for turning the same and this rod works through the bearing 21 and itsinner end carries the eccentric 25. The slot 22 is provided so that theeccentric of the rod 23 may be readily passed therethrough. The operatinrod 23 has the external annular rib 26 wide 'fits against the bearing 21and the thimble 27 surrounding the rod 23 and is screwed into the spiderand abutsthe. rib

' a 26 retaining the rod 23 against displacement. There is a cu shapedstrainer 28 whose margin abuts t e inside of the tub,

said strainer being I openingand the thimble 27 is fitted through thecentral opening in the strainer and has a projecting ange which abutsagainst said strainer and holds it place. he end of theoutlet wasteelbow 4, opposite the pipe 5, has an extensioma's, at 30 and has an inwsideanchor hook 31. A flexible connecting member, such as chain 32, hasthe end hook 33 which engages over the anchor hook 31 and this chainpassesbetween the guides 12 and lies in the grooves 34 in the underside80 of the valve 11 and is retained against displacement by said guidesand the other end 'of the chain has a long link 35 which engages overthe eccentric 25. This chain is) located within the outlet and overflowpipes 25 and is protected thereby. In order to hold the valve 11 closedthe handle 24 may be suitably manipulated to exert a pull on said chainthrou h the eccentric 25 and this will liftthe va ve into closedposition. When :0 the eccentric 25 passes center it will engage againstthe stop 36 so as not to turn far enough to release the chain but tohold it taut and incorporated into the chain there is a pull spring 37which maintains a tension as against said wave valve "11 and when it isdesired to empty the tub the handle 24 may be manipulated inthe otherdirection to release the pull on said chain and the valve 11 willthereby immediately drop to open the 40 waste outlet.

While I have shown and described equipment, as applied to a bath tub itis obvious that it is applicable for use in connection with othercontainers, such as wash basins and the like.

' What I claim is 1. A fluid container having a waste outlet and anoverflow outlet, a downwardly 0 ening valve controlling the wasteoutlet, a ex- I ible member anchored at one end and disposed underneaththe valve and means associated with the overflow outlet and to which theother end of said flexible member is attached through whichsaid membermay be actuated to alternately close, and permit 5 1, some fitted overthe outlet lin 'sai flexible member and adapted to be acthe closin otherend, a valve controlling said waste outlet and mounted on and supportedby said flexible member. I

.3. A bath tub having a waste outlet and an overflow outlet, anactuating rod mounted in the overflow outlet and having an cecentric, aflexible member attached at one end to said eccentric and anchored atits other end to a fixed anchor, a valve control said waste outlet and rnounted above tuat'ed thereby into closed position, and releasedalternatively.

4. A bath tub havinga waste outlet formed with a valve seat, adownwardly opening valve controlling said seat, a flexible memberattached to an anchor at one end and disposed underneath and inoperative connection with said valve, operative means operativelyconnected with said flexible member throlfigh which said member may beactuated to e ect the closing or permit the opening of said valve.

5. A bath tub having a waste -outlet formed with a valve seat, a valvecontrolling said seat, a flexible :member attached to an anchor at oneend and disposed underneath and in operative connection with said saidmember may be actuated to effect the closing or' permit the opening ofsaid valve and a guide for limiting the range of movement of the valve.

I 6. A bath tub having a waste outlet formed with a valve seat, a valvecontrolling said seat, a flexible member attached to an anchor at oneend and disposed underneath said valve, operative means operativelyconnected with said flexible member through which said member may beactuated to effect a or permit the opening of said valve, gui e meansfor limiting the range of movement of the valve, said guide means alsoforming means for retaining said flexible member in operative connectionwith said valve.

7. A bath tub having a waste outlet formed with a valve seat, "adownwardly openingvalve controlling said seat, a flexible memberattached to a fixed anchor at one end and extending around underneathsaid valve, operative means operatively connected with said flexiblemember through which said member may be actuated to efiect the closingor permit the opening of said valve and a yieldable element incorporatedinto said flexible member.
